LGAD and 3D as timing detectors

Perspectives for particle identification in ALICE using silicon-based timing detectors

“…There are currently multiple technologies under development for high-performance timing sensors. LGAD devices, which have been developed for high-energy physics and are going to be part of the LS3 upgrades of ATLAS and CMS, have proven to be able to provide 20-30 ps resolution also with high radiation loads up to 10 13−14 1 MeV neutron equivalent [6]. SPAD sensors are another possibility for precision timing and come with the advantage of being produced in industrialised facilities and therefore with the possibility to have developments for an integrated monolithic sensor technology [7].…”
